[self presentModalViewController:navController animated:animated];

Answer 1

You can disable the slide-up animation like this:
[self presentModalViewController:navController animated:NO];
Then you can provide your own animation code:
navController.view.frame = CGRectMake(320, 0, navController.view.frame.size.width, navController.view.frame.size.height);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
navController.view.frame = CGRectMake(0, 0, navController.view.frame.size.width, navController.view.frame.size.height);
[UIView commitAnimations];
This example gives you the "Fly-in" from right with a smooth speed-curve.
Another way is using the built in slide-in from right with navigationcontroller:
[self.navigationController pushViewController:navController animated:YES];
In this one, your top-viewcontroller needs to be a UINavigationController and it's rootcontroller needs to be your viewcontroller. Then you can push other viewcontrollers.

I have done this and its working for me try ths:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.6];
[UIView setAnimationDelegate:self];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.View2.superview cache:YES];
[self.View2 removeFromSuperview];
[self performSelector:#selector(replaceViews2) withObject:nil afterDelay:0.6];
[UIView commitAnimations];
